White smoke usually indicates a bad head gasket allowing coolant to get into the combustion chamber. Check to see if the coolant is low. Also, you may want to have a compression test done to see if there is a weak cylinder indicating a blown head gasket.

Servicing the cooling system shouldn't have hurt anything.

Based on what you described, it sounds like coolant is getting into the combustion chamber and burning. The most common cause of this is a bad head gasket.

Is it possible that oil residue on my muffler is causing the smoke?

Not if it is coming out of the exhaust.

Good day. I have noticed one more thing. Water from my radiator and reserve tank is draining everyday.

Since that is happening, I am 99% sure it is a head gasket.
